21 Claims.

This invention relates to bathroom fixtures, and more particularly to a unitary structure including a lavatory bowl, a flush tank, supply and drainage connections therefor, and supply and' drainage connections for a bath tub and shower and drainage for a toilet.

It is well known that it requires much time, labor, skill and expense to install the several fixtures of a bathroom. Bathrooms, now being substantially standardized in equipment, it is the object of this invention to standardize a fixture that would be cheap, simple, convenient and easy to install. The fixture is designed to be all inclusive in its plumbing functions. The fixture is designed for use in a variety of types of bathroom constructions in buildings of various structure, old or new. The fixture can be used not only to serve one given bathroom but also to serve fixtures in an adjacent room or on upper or lower floors. An object of the invention, therefore, is the provision of a unit eliminating the numerous plumbing pipes, connections, fixtures and fittings and substituting for them one fixture. This fixture effects interconnection of a bath tub, a shower bath, a lavatory and toilet. The unit is in the form of a casting, in and through the block of which are put passages, conduits and/or channels which function in lieu of piping.

The main portion of the unit is a casting shaped to form a lavatory of a cabinet type. To one side of the casting is placed and connected a bath tub; to the other side is attached and connected a toilet bowl; on the top of the casting may be placed medicine cabinets, mirrors, towel racks, etc.

The upper portion of the casting forms a lavatory bowl and a streamlined projection which forms a shelf and a spout. The streamlined projection holds in its body the lever operating the lavatory drain valve and two faucets for hot and cold water. In the shelf of this streamlined projection is a depression forming a soap dish with a drain and six socket connections for the outside service pipes and one socket for the shower pipe. The upper portion of the casting also forms a flush tank at one side of the lavatory bowl. The flush tank is covered by a lavatory table top.

The casting, being shaped as a lavatory of cabinet type, has shelves, compartments and a hand grip which is an aid for getting into and purposes, the other compartment is a duct for l ventilation from which a low level intake high draught ventilation stack runs up through the height of the casting to draw out odors and moisture. The stack can be equipped with an electric exhaust fan which will increase the draught when needed. The edge of the bottom .of these compartments is recessed to provide toe space so that a person may stand close to the front of the lavatory.

On the side of the casting to which is attached the bath tub is a streamlined projection which holds in its body the lever operating the bath tub drain valve, two faucets for hot and cold bath water and two faucets for hot and cold shower water. In the top of this streamlined projection is a depression forming a soap dish with a drain. In its lower part but above floor level the casting has two socket connections for the bath tub drain pipe and bath tub overflow pipe. On the other side of the casting below the flush tank is the nest for the toilet bowl and the connections for the flush discharge and fo the toilet discharge. 5

On both sides of the toilet bowl are compartments for toilet paper, toilet articles, heater, etc.

In the accompanying drawings I have shown one embodiment of the invention. In this showmg:

Fig. 2 is a plan view of the upper half of the casting showing the supply passages or conduits in dotted lines and omitting the drains and vents for clarity;

Fig. 3 is a plan view of the lower half of the casting showing the drains and vents;

Fig. 4 is a bottom plan view of the lower half of the casting;

Fig. 5 is a front elevation of the unit showing the supply channels and drains and vents in dotted lines;

Fig. 6 is a rear elevation;

Fig. 7 is a side elevation from the left side in Fig. 1;

Fig. 8 is a side elevation from the right side in Fig. 1;

Fig. 9 is a diagrammatic, perspective view of .the supply lines; and s Fig. 10 is a similar view of the drains and vents.

Referring to the drawings the unit consists preferably of a lower casting 2 and an upper casting 4 with a table top 8 arranged on part of the upper casting. The castings may be made of Fig. illustrating the drains and vents.

. alongside the floor. run into other channels for feed of hot and cold any suitable material and may be made in two or more parts. The castings are secured to each other in any suitable way depending upon the material from which they are made. They may be formed of cast metals, sheet metals, porcelain, glass, clay and various plastic compositions. A lavatory bowl Ii is formed in the upper casting and this bowl may be of any suitable shape, and it is contemplated that .it will be of large size. The portion of the upper casting beneath the table 8 forms the flush tank I8 of the toilet. A toilet bowl I2 is attached to the lower casting and as shown may be set at an angle of substantially 45 to the front of the unit. A bath tub I4 is indicated in dotted lines in Fig. 1 of the drawings. The bath tub may be arranged as shown in the drawings or, depending upon the shape of the room, at right angles to the position shown. The unit may be either a right hand unit with the toilet bowl and tub arranged as shown, or may be constructed in the reverse of the illustrated embodiment with the positions of the toilet and tub reversed.

Conduits, forming supply lines for hot and cold water and providing drains and vents for the flush tank, the toilet, bath tub, shower and lavatory bowl, are cast or otherwise formed in the unit, thus eliminating the necessity of pipes and pipe connections except where the unit is connected to the outside sources of supply. These conduits or channels are illustrated separately in Figs. 9 and 10, Fig. 9 illustrating the supply lines and For purpose of illustration they are here shown in the form of tubes or pipes but the passages or channels are actually formed in the castings.

Thus, a hot water channel It extends through -the upper casting terminating at the surface of shelf or projection I8 in the rear of the lavatory bowl and a similar cold water channel 28 is arranged adjacent to it. These channels extend ,portion H (see Fig. 3) of the lower casting to pipes protruding through the floor or coming Within the upper unit they water to the lavatory bowl, tub and shower and for delivery of cold water to the flush tank.

' 'As shown in Fig. 9, the channels I8 and 28 are respectively connected to channels 22 and 25 run- .ning toward the front of the upper unit and, be-

neath these horizontal channels, the channels !6 and 28 are provided with cut-off cocks 26 and 28.

These cocks serve to shut oiT the water supply for the purpose of making connections, cleaning and repairs. A pair of vertical channels 38 and 32 run. into the horizontal channels 22 and 24.

These channels extend to valve casings 34 and 36 arranged adjacent the front of the shelf or prooutlet 48 positioned at the top of the lavatory i bowl as shown in Fig. 1.

Channel 24 runs into channel 48 which extends transversely of the upper casting and at one end runs into the flush tank I8. A cut-off valve 58 is arranged in this channel. A transverse channel 4 jection 58 on the side of the unit over the bath tub. One set of valve casings 68 and 62, arranged within the projection 58, is connected to the'bath tub spout 8 5 by channels'fifi and 68. The valve casings are provided with valves arranged on the opposite faces of the projection 58 and having the usual handles 18 for operation (see Fig. '7). A second pair of valve casings I2 and I4 is also arranged within the projection 58 and these valve casings are connected to a channel I6 which ex- 7 rating mechanism, the details of which are not herein shown, except to indicate, in dotted lines, the valve 88 (see Fig. 5) communicating with a flush channel 86 extending to the toilet bowl. This valve is operated in the usual manner by means of a valve handle 81 arranged on the exterior of the flush tank as shown in Fig. 5.

It will thus be apparent that when sources of hot and cold water are connected to the channels I8 and 28, water may be supplied to any of the component parts of the unit by operation of the usual control valves. The delivery of water may be made to other units in an adjacent room or on floors above or below through connections to the top and bottom conduits I8 and 28 or through connections to the branches I88 and I18 extending to the rear of the unit (see Fig. 6).

The unit also includes a system of drains and vents in the form of channels within the castings and suitably connected to the lavatory bowl, tub and toilet. These are shown diagrammatically in Fig. 10 of the drawings. Thus, thelavatory bowl 8 is provided with a drain comprising, a conduit or channel 88 extending from the bottom of the bowl to a main conduit 98. A drain valve 92 is arranged in the conduit 98 and is connected by an operating rod 98 to the crank or eccentric portion of an operating shaft 96. This shaft projects from the front of the shelf I8 and is provided with an operating handle 98. The upper surface of the shelf I8 is provided with a depressed portion I88 forming a soap dish for the lavatory bowl. The bottom of the soap dish is provided with openings communicating with an individual drain channels I82 (see Fig. 18), which in turn v 52 likewise runs into the hot water channel 22.

These two channels extend upwardly as indicated j'bythe reference numerals 54 and 56 into a procommunicates with the drain 98. A branch conduit I84 communicates by means of a separate channel I 85 with the trap I88. This branch conduit has a spare connection I86 which is normally closed by a plug (see Fig. 6) to provide for connection of other fixtures or units in adjacent rooms. The lower end of the lavatory drain 98 communicates with trap I88, one end of which is provided with a removable cap II8 for access to the trap for cleaning. The trap is connected to a vent pipe I I2 which is in turn connected to the soil stack channel II4 by a channel IIIS which forms the lavatory drain discharge and by a second channel II'I arranged at a higher elevation forming a vent.

The bath tub drains and vents are shown to the right in Fig. 10 of the drawings. As shown in Figs. 1 and 7, a pair of socket connections H8 and I 28 arearranged above the floor level, on the soil stack through the channel I I1.

side of the lower casting where the bath tub is positioned for connection to the bath tub drain pipe and the bath tub overflow pipe. The bath tub drain connection I communicates with a Vertical channel I22 in which drain valve I24 is arranged. A valve rod I26 extends upwardly through the channel and is connected to the eccentric or crank portion of a shaft I28. This shaft is arranged in a horizontal channel I30 extending through the projection 50 and having an operating handle or lever I32 on its end arranged on the front of the projection as shown in Figs. 1 and 7. Also as shown in Fig. 1 the upper surface of the projection 58 is provided with a depressed portion I 34 forming a soap dish for the bath tub. The soap dish is provided with openings I35 communicating with a channel I36 which in turn connects to the channel I30. The

drain pipeconnection I20 and the overflow pipe spare connection is normally closed by a plug or cover I44 on the rear of the lower casting (see Fig. 6). The trap I i-0 is provided with a removable cover I46 for cleaning out purposes. The outlet side of the trap is connected to a discharge channel "I48 leading to the soil stack H4 and is also connected to a vent channel I56. This channel is connected to a cross channel I52, which in turn connects to the lavatory vent I I2 and to the This channel has two spare connections I64 which normally are closed with plugs or covers and which can be used for other fittings or for bathrooms in adjacent rooms or on upper or lower floors.

cates with a trap I54 formed in the lower casting. The toilet bowl drain runs into the soil The channels I48, connecting the soil pipe to vent channels H2 and I50, also serve as venting means in connection with discharge from the toilet bowl. The flush tank is provided with an overflow I56 (see Fig. 5), communicating with "the flush channel 86.

The lower casting is provided with a horizontal channel I 60 communicating with a vertical channel I62 which forms a ventilating duct. This duct may be extended by piping to the outside of the building and provided with a high velocity ventilating fan. This eliminates the necessity of windows in the bath room and thus permits the bath room to be situated in a part of the house not having a direct outlet to the exterior. As shown, the water supply conduits I6 and 20, the

"soil'stac'k I I4, the lavatory vent I I2 and the bath vent I run vertically. This permits a series of units to be arranged on adjacent floors and connected to each other by piping from the top of "one unit to the bottom of the next. below the bottom unit of a series is prevented by Flow of water closing cocks 26 and 20. The upper ends of the vents H2 and I50 and of the soil stack II4 are,

of course, connected to suitable piping extending to the exterior.

heretofore'been described and are illustrated in Fig. "I. A spare connection from vent I50 may extend to the rear of the upper casting and is normally closed by a plug or cover I64, A spare connection from the lavatory vent I I2 may like wise extend to the rear of the upper casting and is normally closed by a plug or cover I66. A spare connection from the lavatory overflow may likewise extend to the rear of the upper casting and is normally closed'by a plug or cover I06. The hot and cold water channels I6 and 20 may be provided with connections extending to the rear of the upper casting and normally closed by plugs I68 and I10. A spare connection to the lavatory trap may extend to the rear of the upper casting and is normally closed by a plug I12. A spare connection from the bath discharge may extend to the rear of the lower casting and is normally closed by a plug I44. A spare connection from the soil stack may extend to the rear of the lower casting and is normally closed by a plug I16.

At the front of the lower casting below the lavatory bowl I preferably provide a shelf I18 for sponges, etc, and this shelf is provided with an opening I at the side to permit access to it from the tub. The provision of this opening also provides a portion I82 which serves as a sturdy hand grip when getting in and out of the tub. Beneath the shelf I18 I provide a series of shelves I84 for towels, toilet articles, etc. In the space below the lower shelf I 04, not occupied by the ventilating duct I60, I provide an additional shelf I66. Also in the lower casting below the flush tank at the one side of the toilet below the space which would otherwise be unoccupied is formed a shelf I88.

On the side of the unit beyond the toilet bowl I I also provide a series of compartments (see Fig. 8). In the upper of the two compartments adjacent the toilet bowl shown at I may be arranged a suitable holder for toilet paper and the compartment I92 immediately below it may be utilized for the storage of toilet paper. The compartment l 94 may be utilized for the provision of an electric heater.

Above the unit I may provide suitable mirrors, lighting fixtures, towel racks, etc. The end of the upper casting over the compartments I 94 may be provided with suitable holders or sockets I96 (see Fig. 5) for towel rods I98, the other ends of which may be secured in sockets or holders 200 in the end wall of the bath room.

In addition to the advantages of the invention which are apparent from the preceding description, attention is called to the fact that all of the conduits are straight lines and are therefore easy to manufacture and easy to clean. The ends of the conduits or channels are threaded either for connection to outside pipes or to the other parts with which they cooperate. The castings are made to require as little machining as possible and can be cast from cheap materials such as cast iron. The provision of the channels through the material of which the casting is made eliminates the use of numerous pipe joints and therefore the possibility of leaks.
